There is a fix for this build failure in the stable-2.12 branch but it 
is not part of a point release yet. In the meantime, you can build 
modules from the git branch or use the package from the "Latest Stable" 
ppa [1].

Once the next point release (2.12.3) happens, it will be uploaded 
straight away to the 2.12 ppa.
